And if you ensure all 1-3 digits groups are in the vocab, it does much better. Both https://arxiv.org/abs/2503.13423 and https://arxiv.org/abs/2504.00178 (co-author) both independently noted that you can do this with just by modifying the pre-tokenization regex, without having to explicitly add commas.&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/2402.14903/"&gt;Paper and discussion history&lt;/a&gt;.

It does make sense to me the R2L chunking would be better than L2R chunking. It doesn&amp;#x27;t actually study single digit tokenization. I am mostly interested in a direct comparison between an LLM wide tokenization vs single digit tokenization. It would be nice to see a direct comparison between similarly trained models. Otherwise it is very hard to get a definitive answer by comparing models with varying sizes, training time, and general strength. &amp;gt; xVal: A…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/2402.14903/"&gt;Paper and discussion history&lt;/a&gt;.
